5.9L-6.7L Pistons Thermal Barrier Coated Dish and Teflon coated Skirt
With the thermal barrier coating in the dish, it protects the piston dish against possible overheat & melting conditions found in todays high exhaust gas temperature applications.
With the Teflon coating on the skirt, there is less friction at start up. Cylinder wall & piston skirt scuffing & gaulding are greatly reduced. It's used in all performance applications & is particularly used by Cummins in all high horse power marine applications.
A great durability upgarde all in all.
